[Structure of partition]
FIG. 4 is an enlarged view of the periphery of the partition 7 or the first partition 7a of the chair-type massage machine 1 according to one embodiment of the present invention, and (a) is an enlarged view of P2 in FIG. 2 (a). (b) is an enlarged view of P3 in FIG. 2(b).

As shown in FIGS. 1 and 2, the partition 7 has a symmetrical shape (see FIG. 2). Since the partitioning portion 7 is symmetrical, the right partitioning portion 7 will be described, and the explanation of the left partitioning portion 7 will be omitted.
The partition portion 7 is arranged above the backrest portion 3 and at a position overlapping the side wall 99 in the left-right direction. The partition part 7 is composed of a plate-like member and has a substantially U-shape with an opening on the left side when viewed from the top. The partition portion 7 is attached to the backrest portion 3 by the first biasing means 15 a and the attachment portion 41 . More specifically, it is attached to the side surface of the backrest 3 (more specifically, the outer surface of the side wall 99 attached to the backrest 3) by the first biasing means 15a. It is attached to the rear surface of the backrest portion 3 by the attachment portion 41 . Note that the mounting portion 41 may be provided on the side surface of the backrest portion 3 .

The rear side of the partition portion 7 is attached to the backrest portion 3 . Specifically, it is mounted so that the position can be changed in the left-right direction via the mounting portion 41 . A mechanical first position changing means a1 may be provided inside the mounting portion 41 (see FIG. 4). Details will be described later.

A sensory stimulation device 100 that provides a relaxing effect to the user may be attached to the inner surface of the partition section 7 (the surface facing the user; more specifically, the front surface of the user) (see FIG. 1, etc.). The sensory stimulation device 100 is, for example, an LED that provides a relaxing effect with light. It is also a display for displaying images and videos. It is also a speaker that provides a relaxing effect with music and voice. Any device may be used as long as it can stimulate the user's senses (in particular, visual, auditory, and olfactory).

For example, the user's front view is partly blocked by the partition 7, and the LED is turned on while the amount of stimulation received from the outside is adjusted. By doing so, an extraordinary space can be created, so that the user can be more relaxed. A part of the front view of the user is blocked by the partition part 7, and the display and the speaker are driven while the amount of stimulus received from the outside is adjusted. By doing so, it is possible to give the user a sense of realism as if he or she were watching an image in a movie theater.

Also, the massage operation (massage course) and the sensory stimulation device 100 (for example, LED) may be configured to work together. For example, a morning massage course and a night massage course are provided. When the morning massage course is selected, the light from the LED is gradually increased as the course starts. By doing so, it is possible to smoothly guide the user to an active state by the massage action and the light while preventing damage caused by suddenly applying strong light to the user. In addition, when the night massage course is selected, the user can be smoothly guided to a relaxed state by adjusting the LED light that cuts visible light, such as blue light, which is strongly irritating to the eyes. .

The shape of the partition part 7 is an example, and may be any shape as long as it can block at least a part of the user's forward field of vision. For example, it may have a capsule shape that covers the upper part of the user. The capsule shape not only blocks part of the forward vision of the user, but also reduces the amount of stimulation the user receives from above.
Further, as shown in FIG. 10, a position changing means (driving mechanism C4) for changing the shape of the partitioning portion 7 may be provided on the front side of the partitioning portion 7 . By doing so, it is possible to prevent obstruction when the user sits on or leaves the chair-type massage machine 1 . It should be noted that the position of the partition section 7 may be changed automatically. Details will be described later.

[Configuration of first position changing means]
The first position changing means a1 changes the position of the partition portion 7 in the horizontal direction with respect to the backrest portion 3. As shown in FIG. The first position changing means a1 is provided with a first urging means 15a for urging the partition portion 7 in a direction to approach the backrest portion 3. As shown in FIG. As shown in FIGS. 2 and 3, the first position changing means a1 is composed of an air cell and a first biasing means 15a.
The air cell is attached between the backrest portion 3 and the partition portion 7 with the rear side in the front-rear direction as a fulcrum so that the front side in the front-rear direction expands. More specifically, the air cell is attached to the backrest portion 3 . In addition, the air cell may be attached to the partition portion 7 . Moreover, the mounting method of the air cell is an example, and any method may be used as long as the position of the partition portion 7 can be changed in the horizontal direction with respect to the backrest portion 3 . For example, the front side in the front-rear direction may be used as the fulcrum.
When the air cell is inflated, the air cell comes into contact with the partitioning portion 7 and the position of the partitioning portion 7 can be moved away from the backrest portion 3 . Since the partition part 7 is biased in the direction of approaching the backrest part 3 by the first biasing means 15a, when the air cell is contracted, the partition part 7 is moved in the direction of approaching the backrest part 3. move to
It should be noted that the configuration of the first position changing means a1 with an air cell is an example, and any configuration can be used as long as the position of the partition portion 7 with respect to the backrest portion 3 can be changed in the left-right direction. good too.

Also, the first position changing means a1 may be of a mechanical type. As shown in FIG. 4, the chair-type massage machine 1 is provided with mechanical first position changing means a1 (driving mechanism C1) inside the mounting portion 41 . The drive mechanism C1 is composed of a motor 20a, a pinion 20b, and a rack 20c. The drive of the motor 20a is controlled by the controller 9. FIG. The motor 20 a and the pinion 20 b are provided inside the mounting portion 41 . The rack 20 c is provided inside the partition section 7 . The pinion 20b meshes with the rack 20c. By driving (rotating forward) the motor 20 a , the pinion 20 b rotates counterclockwise, and the rack 20 c meshing with the pinion 20 b moves away from the backrest 3 . By doing so, the partition portion 7 can be moved away from the backrest portion 3 . By driving (reversing) the motor 20 a , the pinion 20 b rotates clockwise, and the rack 20 c meshing with the pinion 20 b moves toward the backrest 3 . By doing so, the partition portion 7 can be moved in a direction approaching the backrest portion 3 .

By configuring the first position changing means a1 with the mechanical drive mechanism C1, the position of the partition portion 7 can be adjusted without being affected by the first biasing means 15a even when the drive mechanism C1 is stopped. It can be kept in a stopped position.
Further, by increasing the length of the rack 20c provided inside the partition 7, the movement range of the partition 7 can be increased. By doing so, it is possible to save space compared to the case where the first position changing means a1 is composed of an air cell. The first position changing means a1 provided in the backrest portion 3 may be the air cell only, the drive mechanism C1 only, or the air cell and the drive mechanism C1 together.
